Acid Protease AP-050 in Liquid Form

Halal and Kosher Certified

Description

Acid Protease AP-050 is produced from selected strains of Aspergillus niger through submerged fermentation, extraction and refining processes.
It can catalyze hydrolysis of plant and animal proteins under
acidic conditions.

AP-050 has found its wide application in food industry, including
alcohol, fermentation, brewery, beer and wine production.

Applications and Benefits

[Alcohol Production]

Use of AP-050 in alcohol production from starch materials can speed
up the fermentation and uplift yields of alcohol.

[Beer Production]

Use of AP-050 in beer production can decrease the diacetyl content,
thus shorten the brewing time.

Effect of pH and Temperature

Effect of pH

The effective pH range for AP-050 is 2.0∼6.0. Its optimum pH range
is 2.5∼3.5. See Figure 1.

Effect of Temperature

AP-050 can work at 30°C∼65°C (86∼149oF), with an optimum temperature range 40oC∼50°C (104oF ∼122oF). The exact temperature optimum depends on actual processing
time, pH, substrate nature and concentration. See Figure 2.

Effect of Metal Ions

AP-050 is activated by Mn2+, Ca2+ and Mg2+ ions whilst inhibited by heavy metal ions such as Cu2+, Hg2+ and Al3+.

Storage & Shelf-life

AP-050 has been specially formulated for optimal stability.

Typical shelf-life is six months if this product is stored at 0∼
10°C in its original packaging, sealed and unopened, protected from
the sunlight. Prolonged storage and/or adverse conditions such as
higher temperatures may lead to a higher dosage requirement, thus
should be avoided.
